Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, it relates to the drainage device of breathing machine pipeline condensate water collector. BACKGROUND

[0002] The breathing machine plays an important role in the treatment process of critical patients, can effectively correct hypoxemia, and save the patient's life.

[0003] Affected by the ambient temperature, the generation of breathing circuit condensate water is inevitable, in order to avoid the backflow of condensate water into the airway, the water cup is installed in the breathing circuit to collect condensate water, but the condensate water is stored too much and not poured in time, which will make the pipe inner diameter reduce, thereby increasing the airway resistance. When the pipe diameter is reduced by 1 times, the airway resistance will increase by 16 times! The increase of airway resistance will increase the respiratory work of the patient, and the tidal volume will decrease. It is necessary to pour the condensate water in the breathing machine pipeline in time. At the same time, there is a risk of " occupational exposure" in pouring the condensate water.

[0004] On the one hand, when the water cup is disconnected, the condensate water carries a large amount of airway secretions, forms aerosol and diffuses in the surrounding air, or splashes in the process of pouring the condensate water, causes virus transmission, especially when nursing special infectious disease patients, the consequence of occupational exposure caused by the treatment problem of breathing machine condensate water is more serious.

[0005] Therefore, based on the above technical problems, the technical personnel in the art need to develop a drainage device for breathing machine pipeline condensate water collector. CONTENT OF THE UTILITY MODEL

[0021] A limiting protrusion arranged on the first push rod and opposite to one end of the sealing ball; and

[0022] A compression spring sleeved on the first push rod and compressed between the guide sleeve and the limiting protrusion.

Specific implementation

[0039] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with the drawings.

[0040] Referring to Figures 1 to 4 The figure shows;

[0041] The embodiment discloses a drainage device of a condensate water collector for breathing machine pipeline, which comprises a water cup 1 and a breathing machine pipeline 2 connected to the water cup 1 through a three-way pipeline, wherein the breathing machine pipeline 2 is a breathing loop pipeline of a breathing machine, and the water cup 1 is arranged to collect condensate water generated in practical use; however, the water cup 1 is too small in size, and is quickly filled with condensate water during use, so that the condensate water needs to be frequently poured out, which may further cause a risk of “occupational exposure”; in order to avoid the above-mentioned risk, the drainage device is designed, and therefore the device for draining condensate water of the condensate water collector for breathing machine pipeline further comprises:

[0042] A water collecting transfer chamber 3 is arranged in communication with the water cup 1 through a first pipeline 4, and a water outlet 5 is arranged at the bottom of the water collecting transfer chamber 3;

[0043] A condensate water collecting bag 6 is arranged to collect condensate water.

[0044] Specifically, the condensed water in the water cup 1 is first drained to the water collection and transfer chamber 3 through the first pipeline 4. The water collection and transfer chamber 3 plays a role of transferring the condensed water. The condensed water reaching the water collection and transfer chamber 3 is finally transported to the condensed water collection bag 6 for collection. Therefore, the condensed water collection bag 6 is a container with a large loading capacity, which can avoid frequent pouring of condensed water and more avoid causing the risk of "occupational exposure". Moreover, the condensed water collection bag 6 can be made of disposable material and can be replaced.

[0045] The first connecting pipe 7 has one end connected to the bottom of the water collection and transfer chamber 3 and communicated with the water outlet 5 and the other end as a flared end;

[0046] The second connecting pipe 8 has one end communicated with the condensed water collection bag 6 through the second pipeline 9 and the other end as a flared end. The flared end of the second connecting pipe 8 is sleeved on the flared end of the first connecting pipe 7 and is threadedly connected with the first connecting pipe 7. That is, the first connecting pipe 7 and the second connecting pipe 8 belong to components for communicating the water collection and transfer chamber 3 and the condensed water collection bag 6, realizing the dismounting and replacement of the condensed water collection bag 6 from the water collection and transfer chamber 3.

[0047] The opening and closing valve structure is arranged in the first connecting pipe 7 to close the water outlet 5; and

[0048] The opening and closing trigger structure is arranged in the second connecting pipe 8 to trigger the opening and closing action of the opening and closing valve structure.

[0049] The opening and closing trigger structure makes the opening and closing valve structure have two working states: one is that when the second connecting pipe 8 is threadedly connected with the first connecting pipe 7, the opening and closing trigger structure triggers the opening and closing valve structure to be in the open valve state to make the water outlet 5 not be closed by the opening and closing valve structure; the other is that when the second connecting pipe 8 is dismounted from the first connecting pipe 7, the opening and closing trigger structure triggers the opening and closing valve structure to be in the closed valve state to make the water outlet 5 be closed by the opening and closing valve structure.

[0050] Specifically, the opening and closing valve structure cooperates with the opening and closing trigger structure. In the process of realizing the dismounting and replacement of the condensed water collection bag 6 from the water collection and transfer chamber 3 through the dismounting of the first connecting pipe 7 and the second connecting pipe 8, the opening and closing valve structure can temporarily close the water collection and transfer chamber 3, so that the water collection and transfer chamber 3 can uninterruptedly collect the condensed water in the water cup 1, avoiding the excessive accumulation of the condensed water in the water cup 1. Moreover, the closure of the water collection and transfer chamber 3 will not cause leakage, avoiding the risk of "occupational exposure" and making the drainage device more safe to drain the condensed water in the water cup 1.

[0051] Further, the one-way valve 10 is arranged on the first pipeline 4 to make the condensed water only enter the water collection and transfer chamber 3 from the water cup 1. The one-way valve 10 avoids the backflow of the condensed water in the water collection and transfer chamber 3 to the water cup 1.

[0052] Further, the opening and closing valve structure comprises:

[0053] A sealing ball 11 is arranged in the water collecting and transferring cavity 3 to block the water outlet 5. The sealing ball 11 can be a rubber ball with good sealing effect, and a part of the ball structure can extend into the water outlet 5 to block the water outlet 5.

[0054] A first push rod 12 is arranged axially inside the first connecting pipe 7.

[0055] A guide sleeve 13 is arranged inside the first connecting pipe 7. The outer surface of the guide sleeve 13 is connected and supported with the inner wall of the first connecting pipe 7 through the first supporting rod 14. The first push rod 12 is arranged in the guide sleeve 13 and slides in the guide sleeve 13. The first push rod 12 drives the sealing ball 11 to block and unblock the water outlet 5 through axial movement.

[0056] A limiting protrusion 15 is arranged on the first push rod 12 and opposite to one end of the sealing ball 11.

[0057] A compression spring 16 is arranged on the first push rod 12 and compressed between the guide sleeve 13 and the limiting protrusion 15. The compression spring 16 is always in a compressed state. Under the elastic action of the compression spring 16, the first push rod 12 drives the sealing ball 11 to block the water outlet 5. That is, when the first push rod 12 is not under the external force of the compression spring 16, the sealing ball 11 is always in the state of blocking the water outlet 5.

[0058] Further, the opening and closing trigger structure has two working states of the opening and closing valve structure. Specifically, when the first push rod 12 is axially pushed to compress the compression spring 16, the first push rod 12 drives the sealing ball 11 to unblock the water outlet 5 to open the water outlet 5. When the first push rod 12 is released and driven by the elastic force of the compression spring 16 to pull the sealing ball 11 to block the water outlet 5.

[0059] Further, the opening and closing trigger structure comprises:

[0060] A supporting plate 17 is arranged inside the first connecting pipe 7. The supporting plate 17 is connected and supported with the inner wall of the first connecting pipe 7 through the second supporting rod 18.

[0061] A second push rod 19 is perpendicularly connected to the supporting plate 17 to push the first push rod 12. When the second connecting pipe 8 is screwed and tightened on the first connecting pipe 7, the second push rod 19 pushes the first push rod 12 to drive the sealing ball 11 to block the water outlet 5.

[0062] Further, the opening and closing trigger structure makes the opening and closing valve structure have two working states, specifically: in the process of screwing the second connecting pipe 8 on the first connecting pipe 7, the second push rod 19 abuts against the first push rod 12 and axially pushes the first push rod 12 to move until the sealing ball 11 is separated from the water outlet 5, so that the water outlet 5 is opened; in the process of reversely rotating the second connecting pipe 8 relative to the first connecting pipe 7 to separate the second connecting pipe 8 from the first connecting pipe 7, the second push rod 19 moves away from the first push rod 12 and drives the first push rod 12 to pull the sealing ball 11 to close the water outlet 5 under the elastic force of the compression spring 16.

[0063] In the process of screwing the second connecting pipe 8 on the first connecting pipe 7 or unscrewing the second connecting pipe 8 from the first connecting pipe 7, the second connecting pipe 8 has an axial stroke relative to the first connecting pipe 7, but the sealing ball 11 closes the water outlet 5 in a linear sealing mode, and the water outlet 5 is opened and the stroke passage is unblocked instantaneously when the sealing ball 11 is separated from the water outlet 5. Therefore, when the second connecting pipe 8 is just sleeved on the first connecting pipe 7 and has not been rotated, the length of the second push rod 19 is set to not contact the first push rod 12, and when the second connecting pipe 8 is rotated by a distance to have a sealing effect and have the ability to guide the condensed water, the second push rod 19 contacts the first push rod 12 and pushes the first push rod 12, so that the sealing ball 11 is separated from the water outlet 5 and the water outlet 5 is opened. Similarly, in the process of unscrewing the second connecting pipe 8, the second connecting pipe 8 and the first connecting pipe 7 are still threadedly connected after the sealing ball 11 closes the water outlet 5, and the second push rod 19 is separated from the first push rod 12 by continuing to rotate the second connecting pipe 8.

[0064] In the above technical solution, the drainage device for the condensate water collector of the breathing machine pipeline has the following beneficial effects:

[0065] The water collecting and transferring cavity and the condensate water collecting bag can collect a large amount of condensate water, so that the condensate water in the water cup can be timely emptied, the normal work of the breathing machine is avoided from being affected, and when the condensate water is poured, the connection part of the condensate water pipeline is timely closed by the opening and closing valve structure after being disassembled, the condensate water collecting bag is reasonably discarded, the condensate water in the water cup continues to be received by the water collecting and transferring cavity during replacement of a new condensate water collecting bag, the "occupational exposure" risk is avoided from being caused, the condensate water in the water cup is more safely discharged by the drainage device.

[0066] The above only describes some exemplary embodiments of the utility model by way of illustration, without doubt, for ordinary skilled persons in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the utility model. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the utility model claims.
